The FE-128 contains the same 12mm (1/2 inch) aluminized-mylar diaphragm as the FE-120. This mic's smooth frequency response and overall warm sound makes it suitable for a wide variety of sources. The FE-128 has additional frequency response shaping circuitry and a different physical construction than the FE-120. The FE-128 is optomized to give a larger-than-life sound. It's low self-noise makes it great for quiet situations, even as a diffuse-field mic. It won't clip at SPL levels higher than anyone's ears could ever handle! Just like the rest of the FE-series mics, it is extremely compact, so it's great for an unobtrusive live recording setup or for fitting into tight spaces. With the replaceable capsule feature, this microphone still measures in at just 4 inches in length!

Op-Amp Based Preamplifier:
These microphones are made standard with a Burr Brown OPA-134 opamp. This opamp provides excellent audio performance, low noise, and low power consumption. If you have a particular interest in opamps, we give you the option to choose whatever opamp you want to be used, and we will put it in for you. That way, you can fine-tune the sound of our microphone to your liking. See our Info page for a selection of opamps.

The FET utilized as the first amplification stage in the FE-128 has been selected from a large sample group, for best noise performance. Additionally, the pad in this microphone takes effect before the FET stage, so this microphone can handle SPL levels up to 159dB!

Reliability:
Precautions were taken to ensure reliability, despite the addition of the removable capsule. The spring contact to the capsule is gold plated to prevent corrosion. The capsule/preamp joint is manufactured precisely so that the capsule will make contact with the preamp several full turns before it is tightened. The high impedance terminal is held in place by a Teflon spacer, and it is shielded from all sources of interference.

With proper care (a microphone is a precision tool after all, and should be treated as such) our microphones will last for many years, without any maintenance required! Just in case, we offer a five year warranty for any problems you might have.

Internally biased capsule:
The capsule is a back-electret design. The charge-holding electret material is located on the backplate, and not on the diaphragm. The diaphragm can be manufactured using the same process and materials as a standard condenser microphone. The low quality sound commonly associated with electret microphones doesn't apply here!
